TECHNICAL FIELD

The present invention relates to a method and a device with fuel for combustion that is used in the sectors of industry, canteen and power plant, in particular, relates to an energy-saving, efficient and environment- friendly fuel-combustion method and device.

TECHNICAL BACKGROUND

Currently, for the existing fuel burners, during the operation, the fuel is sent by a pipe to the furnace (or devices), which is ignited and then directly burns in the furnace. The common defect of such fuel burners is: more than 50% of the valuable fuel has not yet reached the complete combustion before being discharged to the living space, which contains the thermal radiation, carbon dioxide, nitrogen dioxide, carbon monoxide, nitrogen oxides and sulfides etc. that form the main cause of acid rain, resulting in the leading culprit, blamed for the damages to the human living environment, or even the root that endangers the human life.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A fuel-combustion energy-saving method, where the combustion method is:

1> An input port lets the fuel enter into the furnace, where the fuel is ignited to bring forth the incomplete combustion:

2> Another input port is used for adding the supplementary fuel to the furnace, which is mixed with the early-coming fuel in the furnace that is burning to bring forth the complete combustion;

3> The burning fuel experiences the phenomenon of cracking, gasification and expansion, but it is restrained in the furnace for compression, resulting in the fusion reaction for the purpose of perfect combustion;

4> Synchronized with the above steps, the air taken from the furnace side wall is mixed with the burning fuel in the furnace, which makes the heat generated in the furnace is erupted due to the combustion.

An embodiment of above method of the non-thermal-radiation fuel burner is shown in FIG. 1, which comprises a furnace 1 with a hearth 2 inside, and the furnace 1 and heart 2 are so configured to form an air channel 11. The hearth consists of a shell with multiple through-holes 3, and the hearth 2 contains the primary combustion chamber 21, secondary combustion chamber 22 and blocking chamber 23. The hearth is provided with two input ports 9 which are connected with a connection pipe respectively, one pipe connects the low end of primary combustion chamber 21, and the other connects the low end of the secondary combustion chamber 22. The primary combustion chamber is divided into the lower/upper shells 211, between which there are through-holes 4 as the connection channel; the shells 211 are distributed with plural through holes 5 that connect the secondary combustion chamber 22, and there is a igniter 10 at the lower part of the primary combustion chamber 21; the secondary combustion chamber 22 is a compartment formed by the shell 211 of the primary combustion chamber 21, separation plate (6) with plural through-holes on shell 211, and hearth 2; the blocking chamber 23 is formed by the sealing plate 7 of the furnace body 1 and the separation plate 6 that is provided with the flame holes 71, where the flame holes 71 are configured to be at a acute angle with the center axis to facilitate the scattering and eruption of the flame; there are the air flow through-holes 8 relevant to the flame holes on the separation plate 6 and sealing plate 7, and the air flow through-holes 8 directly connect the secondary combustion chamber 22 and the blocking chamber 23.

The lower shell of the primary combustion chamber 21 consists of two or more support legs 212 that are provided with plural through-holes 51.

The following is a more detailed description in combination with the non-thermal-radiation fuel burner and the principle.

During the operation, fuel is sent in the primary combustion chamber 21 through the input port 9, and the igniter 10 is activated, then the flame maintains the basic combustion temperature and ignition point in the combustion chamber to bring forth the preliminary incomplete burning, so that the fuel in the combustion chamber experiences continuous cracking and gasification; at the same time, oil is supplemented to the secondary combustion chamber 22 through another input port 9, which is heated by the flame due to the fuel burning in the primary combustion chamber 21, and is mixed with the air taken from the air flow through-holes 8 in the sealing plate 7, so the fuel experiences instantaneously cracking and gasification to bring forth the intermediate complete combustion; then the fuel enters the blocking chamber 23; since the sealing plate 7 of the blocking chamber 23 is provided only with the flame holes 71 that allows the flame flows out the furnace body 1, the fuel cannot erupt out the furnace body 1 instantly, but blocked in the furnace body 1, so the fuel that is burning in the furnace body experiences further continuous repeated gasification, compression, and cracking to produce more thorough fusion, so that the inherent energy of the fuel ingredients is converted into thermal energy and then released, and so there is no radiation to carry out the energy from the bright flame, which achieves advanced and perfect combustion. Finally, the flame erupts from the flame holes in the sealing plate 7 of the blocking chamber 23, so the erupted flame carries with only the high temperature, while the radiation is thoroughly eliminated—if the hand is placed near the flame, it still feels cool without being scalded.

It is informative from above description, the non-thermal-radiation fuel burner allows more perfect and complete combustion, which is unlikely to extinguish even at the small feeding rate of 20 mlS/min under the enclosed condition. The releasable temperature is as high as 1350° C. The energy consumption rate is 50% lower than the similar devices, or even better, while the emission of harmful gases is greatly reduced, which even can simplify the gas catalytic transformation procedure to allow a clean heat recovery.
